Hi,
That's a microtome. It was used for cutting samples to view under a microscope. Most commonly you'll see Puma's like this. I think a few of the guys have had limited success on getting them to shave. They're a similar grind to a japanese blade, so it would be easier to shave someone else than yourself, as they perform better on one side than the other.
Have a look at this, & the linked threads.

If it is bent though, you'll struggle to do anything with it.
